If you go to www.jamestowndistributors.com web site, you can download the
MSDS (Material Safety Data Sheet) for this paint. I downloaded the MSDS
for the white smooth (rather than hammered texture) brush-on paint, and it
said that the thinner in the paint consists primarily of xylene (16.5
percent of the can's weight is xylene) and acetone (4.3 % acetone).
Now, acetone evaporates much more rapidly than xylene, so it's kinda dumb
to use acetone as a thinner in a paint that's not meant to be sprayed.
The only reason I can think of to use some acetone in this paint is that
acetone is NOT considered a VOC so far as the US air pollution watch dogs
are concerned. So, by replacing some of the xylene thinner in the paint
with acetone, Masterchem (who is the company that makes this paint) can
both keep the paint below the stringent VOC guidelines in the US, AND
advertise that this paint has lower VOCs now, and is therefore "greener".
But, as soon as you open the can and start painting with the paint, that
acetone is going to evaporate fairly quickly out of the can, and what
you'll be left with is a thicker paint of higher viscosity that won't self
level as well.
Go to any paint store and buy some xylene and use that to thin your
Hammerite paint. You don't need to add much because thinning paint is
like burning the candle at both ends; not only will the added thinner slow
the drying time of the paint, but it will also lower the paint's viscosity
and thereby allow it to self level faster. So, you don't need to thin the
paint much to notice a difference in it's performance.
Because of tight VOC regulations on paints in the US, lots of paint
companies find themselves unable to meet those requirements and resorting
to simply putting less thinner in the paint when making it and slapping a
"Do Not Thin" sticker on the can before it leaves the factory. That's
about the only way they can meet the VOC requirements in order to sell
their paint. When I see that "Do Not Thin" sticker on a can of oil based
paint, I also buy a quart of paint thinner because I know I'm going to
need to thin the stuff before using it in order to get it to work as
Hope this helps.
